I am not a pet owner but in my limited experience the feline of the species is vastly superior to the canine. Let me tell you a story:
A few months ago I was sitting in the bus shelter on my own when approached by a cat miaowing pitifully. I said, "Hello, Pussy," (as you do), which the cat took as my acceptance of it. It kept rubbing itself between my legs, miaowing all the time. What a friendly cat, I thought. Wrong! The reason he was so keen to rub up against my legs was not affection, merely that he wanted somewhere to deposit his fleas! Having done so to his satisfaction he turned his back upon me, tail held high, crossed the road whilst ensuring that I had ample opportunity to view the tea towel holder!
